A variable star has been discoved in TrA, according to the Central Bureau for Astronomical Telegrams (CBET No. 867, Daniel W. E. Green, ed.):

"C. Jacques, Belo Horizonte, Brazil, reports that C. Colesanti, E. Pimentel, T. Napoleao, and he have found a previously unknown variable star on CCD images obtained in the course of the Brazilian Supernovae Survey (cf. IAUC 8482). The new object is located at

V723 Cas was discovered by M. Yamamoto, Okazaki, Aichi, Japan, on 1995 August 24.57 UT at photographic magnitude 9.2. The finding was made using a 200-mm f/4.0 lens, PO0 filter, and T-Max 400 film. A report by G.V. Williams of the Harvard-Smithsonian Center for Astrophysics shows percursory evidence of this nova located on the Palomar red plate of magnitude 18-19, as seen using the Digital Sky Survey (AAVSO Alert Notices 213, 214, 217, 218, 230; IAUC 6213).
